When considering LCT (lactase gene) and weight loss (Abnehmen), the connection is indirect. The LCT variant (e.g., rs4988235) determines lactase persistence: people with the T allele can digest lactose throughout life, while those with the C allele often develop lactose intolerance. Lactose intolerance can cause bloating and discomfort, which might reduce dairy intake and inadvertently lower calorie consumption. However, there is no strong evidence that LCT genotype directly influences weight loss. Some observational studies suggest that dairy consumption (rich in calcium and protein) may support weight management, but this is not genotype-specific. Consumer DNA tests often overstate the role of single genes. For weight loss, focus on overall diet quality, calorie balance, and physical activity. If lactose intolerant, choose lactose-free alternatives to avoid discomfort, but don't expect a magic weight-loss effect from your LCT status.
